We have designed a new synthetic strategy for the preparation of a new class of cyclic RGD integrin ligands in which the azabicycloalkane scaffold can be envisaged as a (gamma,alpha) dipeptide mimic. The synthesis and in vitro biological evaluation of these RGD derivatives, as well as the computational study of their conformational properties and binding modes to alpha(V)beta(3) integrin are described. Compound 3 has shown to be a promising candidate as alpha(V)beta(3) integrin antagonist able to interfere with both cell adhesion and movement on vitronectin with no evidence of cytotoxic effects.

Abstract
We have designed a new synthetic strategy for the preparation of a new class of cyclic RGD integrin ligands in which the azabicycloalkane scaffold can be envisaged as a (gamma,alpha) dipeptide mimic. The synthesis and in vitro biological evaluation of these RGD derivatives, as well as the computational study of their conformational properties and binding modes to alpha(V)beta(3) integrin are described. Compound 3 has shown to be a promising candidate as alpha(V)beta(3) integrin antagonist able to interfere with both cell adhesion and movement on vitronectin with no evidence of cytotoxic effects.File in questo prodotto:
